ABSTRACT OF THE DISCLOSURE Process and composition for forming cellular inorganic plastic cements of magnesium oxychlorides and magnesium oxysul- fates. A water slurry containing a magnesium salt, magnesium ox- ide and a water-soluble phosphate is formed and to it are added an anionic water-repellent surfactant and hydrogen peroxide as a blowing agent. A decomposition catalyst for the hydrogen per- oxide and a nucleating agent may also be added -to the slurry. Inorganic filler materials are added to impart strength to the cellular product which is nonflammable and exhibits essentially zero flame spread, zero smoke density and zero fuel contribution. The cellular product is formed of substantially uniformly sized cells.
